Practically speaking, LCC is a mixture of a mortar
(prepared according to the “fabrication recipe”) and a certain quantity of foam, injected with pressure by the
central unit.

After the homogenization of these components, LCC has
the aspect of foamed concrete, with a viscosityand fluidity alike to sour cream. The pouring of this foamed cement can be made in prints of
miscellaneous dimensions, usually chosen so that they are corresponsive to the usual
dimensions of the ACC bricks (e.g.600x250x200mm).

The foamed concrete (LCC) can be poured just as well
directly into a mould,

for the direct achievement of monolith walls. This choice
is advantaging because of eliminating the hand-made costs for five compulsory operations in laying
out a building: walling up, plastering, picturing electrical installations, and picturing sanitary
applications and carpeting.

-permanent technical assistance in order to
obtain the optimal fabrication recipes

(for free, by mail, e-mail, or phone);

-obtaining the Romanian Technical Agreement (for free);

- warranty and post-warranty service (with
transport and housing prepaid in case of exports ).

The central unit, (any of the presented versions), as well as
the walling bricks fabrication technology and the direct pouring into a monolith wall technology are
certificated, respectively technically approved by MLPAT>Romania. </040-2001.

As steps in the LCC production process, the following
are distinguished:

-preparing
the prints for filling (lubricating them with special liquids or
residual oil);

-loading
the central unit with foaming agent and water in a 2-2,5 percentage;

-loading
cement, sand and water into the concrete mixer, according to the fabrication
recipe for the desired density;

-homogenization
of the mortar into the concrete mixer;

-injecting
the foam into the concrete mixer through a pressure hose connected to the
central unit;

-homogenization
of the mixture (foam and mortar) inside the concrete mixer.

It is good to know that the hardening of this material depends
on the environmental temperature.

The bricks (building blocks) obtained after unfolding (after 24
hours) can be delivered in 2 or 3 days after pouring , although it is best the walling to begin after at least 7 days
since fabrication.

After the putting into function and establishing the final
recipe, our society assumes the obligation of agreeing the product obtained by the beneficiary (on Romanian
standards).

The costs involved by obtaining the technical agreement (for
Romania) are covered by our company.

In this case, the production of LCC becomes legal to the
owner, under the license of FOTON 2000 SELF.

The foaming agent (active and concentrated substance) is an
organic product, non-toxic and biodegradable.

One kilo of foaming agent is
12 RON.

The consumption of foaming
agent, in order to obtain 1 cubic meter,is specified in the
fabrication recipe. It is imported from Italy and can be delivered in any desired
quantity.

For obtaining a good quality
LCC, the involved raw materials must accomplish the following tasks:

-the
sand must have an aggregate grading between 0 and 3 mm, the amount of dusty
parts

as small as possible (below 2%) and
the amount of silicon dioxide as big as possible;

-the
cement, type A II-(X) 32,5 R (Romanian standards), must have no additions;

-the
water used to prepare the foaming solution must be as “clean” as possible,

with very small amount of limestone.

For calculating the necessary costs for producing a cubic meter
of LCC,our advice is to do this for a density of 800-kg/cubic meter,
because this is usually used both for the exterior walls as for the interior ones. So, to the raw
materials’ cost, you have to add the foaming agent’s cost (0,74 l * 1,16 kg/l * 12 RON + taxes),
electrical energy and water consumption costs and conversions costs. If you quote up,
you reach a sum of approximately45-50 USD / cubic meter (including taxes),

which represents 50-60% of the price of a cubic meter of ACC
(in Romania).

There are necessary 6 – 10 square meters of pouring surface for
1 cubic meter of LCC (occupied by moulds and access surface).

Productivity is established depending on the concrete mixers’
capacity in usage (you will obtain bigger productions while using higher capacity
concrete mixers).

For example, with a small concrete mixer of 150 liters you can
produce 1 cubic meter/hour, while with a 500 liters concrete mixer you obtain 2,5-3 cubic
meters/hour.

Any type of concrete mixers can be used for homogenizing the
mixture of mortar and foam, including concrete-stations or auto concrete mixers.

The necessary volume of foam for producing 1 cubic meter of
LCC with a 800 kg/cubic meter density is about 640 liters (c.dm.), meaning 0,74 liters of
concentrated foaming agent.

Also, LCC can be poured as an isolating layer.

For being able to analyze the LCC specific features
referring to corrosiveness, thermal conductivity quotient and water absorption, we must
specify before anything else that the fabrication technology is totally different to the ACC
one,

(ACC is the only material, which LCC can be compared to).

For producing ACC, aluminum powder is used; for
obtaining its cellular aspect,passing through some chemical reactions with the lime as raw material gives off
a certain quantity of hydrogen.

At a microscopic level, each particle of aluminum powder gives
off a volume of hydrogen, which creates a bubble (sphere) with a diameter between 1 and 3
mm.

The bubbles of hydrogen migrate to the exterior (because it is
not a stable gas in its pure state).

The hydrogen’s migration process to the surface is accompanied
by the appearance of some microchannels between holes, set up by expansion.

This aspect is easily detected using the microscope.

ACC is treated in an atmosphere of
saturated vapors, in autoclaves at a pressure of 12 atmospheres and a temperature
of 197 Celsius degrees, for 16 hours in order to be hardened (brought to maturation).

Regarding LCC, the cellular aspect is realized by
injecting the foam bubbles into the sand and cement mortar, without any chemical phenomena.

The lack of microchannels involves a much better LCC
behavior regarding the thermal transfer and water absorbency, compared to ACC.

Also, the lack of lime inside the LCC involves the lack
of corrosiveness.

As a conclusion, the fact that LCC is a coherent system
with spherical bubbles, without microchannels, involves a superior characteristic
towards

ACC thermal isolation and water absorbency.

ACC absorbs water both because of
the capillary channels and the hygroscope character of the lime used in its
preparation.

Another favorable feature of LCC compared to ACC
is the behavior towards the plastering mortar;

at ACC, the presence of lime determines a quick
absorption inside the plastering mortar, which makes a false hard-setting, determining a big probability
of detachment of the ACC bricks from the built-up wall.

In order to realize a high quality plastering, the wall to be
plastered is usually primed with mortar drops, which is a supplementary and expensive operation.

The absence of lime in LCC determines an extremely
facile adheration of the plastering mortar to the wall, which makes possible to deposit a thinner layer than in the
case of ACC.

The superior LCC thermal isolation, compared to the
ACC’s, offers the possibility of building thinner walls with the same thermal comfort as the ones obtained with thicker
ACC walls.
